FIG. 2 is a diagram illustrating an example of an electronic device and a server according to at least one example embodiment. Description is made using the electronic device 110 as an example of an electronic device and the server 150 as an example of a server with reference to FIG. 2. Also, the other electronic devices 120, 130, and 140 or the server 160 may have the same or similar configuration as that of the electronic device 110 or the server 150.

Referring to FIG. 2, the electronic device 110 may include a memory 211, a processor 212, a communication module 213, and an input/output (I/O) interface 214, and the server 150 may include a memory 221, a processor 222, a communication module 223, and an I/O interface 224. The memory 211, 221 may include a permanent mass storage device, such as random access memory (RAM), a read only memory (ROM), a disk drive, a solid state drive (SSD), a flash memory, etc., as a non-transitory computer-readable record medium. The permanent mass storage device, such as ROM, SSD, flash memory, and disk drive, may be included in the electronic device 110 or the server 150 as a permanent storage device separate from the memory 211, 221. Also, an OS or at least one program code, for example, a code for a browser installed and executed on the electronic device 110 or an application installed and executed on the electronic device 110 to provide a specific service, may be stored in the memory 211, 221. Such software components may be loaded from another non-transitory computer-readable record medium separate from the memory 211, 221. The other non-transitory computer-readable record medium may include a non-transitory computer-readable record medium, for example, a floppy drive, a disk, a tape, a DVD/CD-ROM drive, a memory card, etc. According to other example embodiments, software components may be loaded to the memory 211, 221 through the communication module 213, 223, instead of the non-transitory computer-readable record medium. For example, at least one program may be loaded to the memory 211, 221 based on a computer program, for example, the application, installed by files provided over the network 170 from developers or a file distribution system, for example, the server 160, providing an installation file of the application.

The processor 212, 222 may be configured to process instructions of a computer program by performing basic arithmetic operations, logic operations, and I/O operations. The computer-readable instructions may be provided from the memory 211, 221 or the communication module 213, 223 to the processor 212, 222. For example, the processor 212, 222 may be configured to execute received instructions in response to the program code stored in the storage device, such as the memory 211, 221.

The communication module 213, 223 may provide a function for communication between the electronic device 110 and the server 150 over the network 170 and may provide a function for communication between the electronic device 110 and/or the server 150 with another electronic device, for example, the electronic device 120 or another server, for example, the server 160.

Inversely, a control signal, an instruction, content, a file, etc., provided under control of the processor 222 of the server 150 may be received at the electronic device 110 through the communication module 213 of the electronic device 110 by going through the communication module 223 and the network 170. For example, a control signal, an instruction, content, a file, etc., of the server 150 received through the communication module 213 may be transferred to the processor 212 or the memory 211, and content, a file, etc., may be stored in a storage medium, for example, the permanent storage device, further includable in the electronic device 110.

The I/O interface 214 may be a device used for interface with an I/O apparatus 215. For example, an input device may include a device, such as a keyboard, a mouse, a microphone, a camera, etc., and an output device may include a device, such as a display, a speaker, a haptic feedback device, etc. As another example, the I/O interface 214 may be a device for interface with an apparatus in which an input function and an output function are integrated into a single function, such as a touchscreen. The I/O apparatus 215 may be configured as a single device with the electronic device 110. Also, the I/O interface 224 of the server 150 may be a device for interface with an apparatus (not shown) for input or output that may be connected to the server 150 or included in the server 150. In detail, when the processor 212 of the electronic device 110 processes an instruction of a computer program loaded to the memory 211, content or a service screen configured based on data provided from the server 150 or the electronic device 120 may be displayed on the display through the I/O interface 214.

According to other example embodiments, the electronic device 110 and the server 150 may include a smaller or greater number of components than a number of components shown in FIG. 2. However, there is no need to clearly illustrate many components according to the related art. For example, the electronic device 110 may include at least a portion of the I/O apparatus 215, or may further include other components, for example, a transceiver, a global positioning system (GPS) module, a camera, a variety of sensors, a database (DB), and the like. In detail, if the electronic device 110 is a smartphone, the electronic device 110 may be configured to further include a variety of components, for example, an acceleration sensor, a gyro sensor, a camera module, various physical buttons, a button using a touch panel, an I/O port, a vibrator for vibration, etc., which are generally included in the smartphone.

Hereinafter, a method and system for representing a chatroom in a 3D form according to example embodiments is described.

FIG. 3 is a diagram illustrating an example of components includable in a processor of an electronic device according to at least one example embodiment, and FIG. 4 is a flowchart illustrating an example of a method performed by an electronic device according to at least one example embodiment.

A chatroom display system implemented using a computer may be configured in the electronic device 110 according to the example embodiment. For example, the chatroom display system may be configured in a form of a program that independently operates or may be configured in an in-app form of a specific application to be operable on the specific application and may provide a messenger service through interaction with the server 150 depending on example embodiments.

The chatroom display system configured in the electronic device 110 may perform a chatroom display method in response to an instruction provided from an application installed on the electronic device 110. Referring to FIG. 3, to perform the chatroom display method of FIG. 4, the processor 212 of the electronic device 110 may include an event recognizer 310, a screen switcher 320, and an information outputter 330 as components of the processor 212. Depending on some example embodiments, components of the processor 212 may be selectively included in or excluded from the processor 212. Also, depending on some example embodiments, the components of the processor 212 may be separated or merged for representation of functions of the processor 212.

The processor 212 (e.g., the components of the processor 212) may control the electronic device 110 to perform operations S410 to S440 included in the chatroom display method of FIG. 4. For example, the processor 212 (e.g., the components of the processor 212) may be configured to execute an instruction according to a code of at least one program and a code of an OS included in the memory 211.

Here, the components of the processor 212 may be representations of different functions of the processor 212 performed by the processor 212 in response to an instruction provided from a program code stored on the electronic device 110, for example, an instruction provided from an application executed on the electronic device 110. For example, the event recognizer 310 may be used as a functional representation of the processor 212 that controls the electronic device 110 to recognize a screen switch event for a chatroom in response to the aforementioned instruction.

Referring to FIG. 4, in operation S410, the processor 212 may read one or more instructions from the memory 211 to which instructions associated with control of the electronic device 110 are loaded. In this case, the read instruction may include an instruction for controlling the processor 212 to perform the following operations S420 to S440.

In operation S420, the event recognizer 310 may recognize a screen switch event for a chatroom that is a chat interface screen of a messenger installed on the electronic device 110. The chatroom, as an interface screen corresponding to a communication session established between an account of the user of the electronic device 110 and an account of at least one chat partner, may be configured and displayed generally as a screen of a two-dimensional (2D) form. For example, in response to a user's input of a desired or (alternatively, preset) gesture to the chatroom, for example, a 3D touch (e.g., a touch pressure) on a screen of the electronic device 110, the event recognizer 310 may recognize the input gesture as a screen switch event. As another example, in response to a direct selection from the user on a screen switch menu included in the chatroom, linkage to a chat partner list, or linkage a profile, using a touch, the event recognizer 310 may recognize the same as a screen switch event. As another example, the event recognizer 310 may automatically recognize a screen switch event for a corresponding chatroom based on time information set for the chatroom. For example, the event recognizer 310 may recognize a point in time corresponding to 30 minutes before an appointment time set for a chatroom as a screen switch event. As another example, the event recognizer 310 may automatically recognize a screen switch event for a corresponding chatroom based on location information set for the chatroom. For example, if a location of the electronic device 110 arrives at an appointment place set for a chatroom, the event recognizer 310 may recognize the same as a screen switch event. As another example, the event recognizer 310 may recognize a screen switch event for a corresponding chatroom based on a location distribution according to location information of the electronic device 110 and location information of chat partners included in the chatroom. For example, if users included in a chatroom are scattered by a desired (or alternatively, predetermined) desired level or more, the event recognizer 310 may recognize the same as a screen switch event. As another example, if a video call, for example, a Voice over Internet Protocol (VoIP) call starts between users of a chatroom, the event recognizer 310 may automatically recognize a screen switch event for the chatroom.

In operation S430, the screen switcher 320 may switch a screen to display the chatroom in a 3D form in response to recognizing the screen switch event. Referring to FIG. 5, in response to recognizing a screen switch event in a chatroom 510 displayed in a 2D form, the screen switcher 320 may switch the chatroom 510 to a 3D space 520 having desired depth information. Here, the screen switcher 320 may adjust a depth of the 3D space 520 in response to an input of a desired (or alternatively, predetermined) gesture after the chatroom 510 is switched to a 3D form, that is, after the chatroom 510 is displayed in the 3D form. For example, referring to FIG. 6, the screen switcher 320 may adjust a depth of the 3D space 520 through a spread gesture 601 and/or a pinch gesture 602 using two fingers.

Referring again to FIG. 4, in operation S440, the information outputter 330 may output state information associated with the user of the electronic device 110 and state information associated with a chat partner included in the chatroom on the 3D space. Here, the state information may include profile information registered to the messenger. In addition to basic information such as a profile, the state information may further include a new message, a message non-confirmation state, location information or activity information based on the location information, and/or a use status of another service linked to a messenger account. The messenger may include a function of sending and receiving messages through a chatroom, a function of sharing location information or activity information between a user and a chat partner, a function of providing another service (e.g., a music service) to a messenger account, or the like. For example, the information outputter 330 may represent a distance between the user of the electronic device 110 and a corresponding chat partner as depth information on the 3D space based on location information of the electronic device 110 and location information of the chat partner included in the chatroom. As another example, the information outputter 330 may output, on the 3D space, activity information representing a moving state (e.g., moving by walking, moving in a public transportation (e.g., a bus or a subway), or moving in his/her own vehicle). As another example, the information outputter 330 may output a new message received from a chat partner included in a chatroom or a message non-confirmation state on a 3D space. As another example, the information outputter 330 may output an icon representing another service being used for each chat partner included in a chatroom on a 3D space. For example, if a music service is in use, the information outputter 330 may output a corresponding service icon on a 3D space of a chatroom for each chat partner. Here, the information outputter 330 may track a gaze of the user of the electronic device 110 with respect to the 3D space, and may output content being used by a chat partner corresponding to the gaze of the user through an output device (e.g., a speaker and a display) of the electronic device 110.

FIGS. 7 to 13 illustrate examples of a process of displaying state information on a 3D space of a chatroom according to at least one example embodiment.

Hereinafter, description is made by using a chatroom joined by the user of the electronic device 110 and chat partners A, B, C, and D.

Referring to FIG. 7, the information outputter 330 may display a user icon 701 representing the user and a partner icon 702 representing each chat partner on a 3D space 520 having depth information, as the chatroom. Here, the user icon 701 and the partner icon 702 may include a desired (or alternatively, preset) profile image or default image. In the case of the chat partners A and B each of which a location is allowed to be shared with the user, a distance between the user and each of the chat partners A and B may be represented as depth information d_(A) and d_(B) between the user icon 701 and the corresponding partner icon 702. In the case of the chat partners C and D each of which a location is disallowed to be shared with the user, the corresponding partner icons 702 may be displayed around the user icon 701 without depth information. As another example, if orientations or azimuths of the chat partners A and B with respect to the user are verifiable from the location information of the chat partners A and B, the information outputter 330 may display the user icon 701 at the center of the 3D space 520 and may arrange the partner icons 702 based on the orientations or the azimuths of the chat partners A and B verified with respect to the user. As another example, if a video call, for example, a VoIP call between chatroom users starts and a screen is switched to display a chatroom in a 3D form, the information outputter 330 may provide a video call screen using the 3D space 520. Here, the user icon 701 and the partner icons 702 may be configured as a video call screen instead of each profile image.

Referring to FIG. 8, in response to detecting movements of the chat partners A and B each of which a location is allowed to be shared with the user, the information outputter 330 may display each moving state icon 803 at a location adjacent to the corresponding partner icon 702, for example, at a right upper end of the partner icon 702. Here, a moving type, for example, moving by walking, moving in a public transportation (e.g., a bus or a subway), moving in his/her own vehicle, may be classified based on a moving speed or a moving route of a chat partner. Also, the information outputter 330 may display the moving state icon 803 corresponding to the classified moving type. The moving speed or the moving route of the chat partner may be information received from an electronic device (e.g., the electronic device 120) of the chat partner, and may be information calculated by the electronic device 110 of the user from location information of the chat partner received from the chat partner.

Referring to FIG. 9, in response to receiving a new message from the chat partner A through a chatroom, the information outputter 330 may display a speech balloon 904 for a desired (or alternatively, predetermined) period of time (e.g., 3 seconds) at a location adjacent to the corresponding partner icon 702, for example, at a right upper end of the partner icon 702. Here, if the user taps the speech balloon 904 for the desired (or alternatively, predetermined) period of time, the speech balloon 904 may be processed to be confirmed. If the desired (or alternatively, predetermined) period of time is elapsed without tapping the speech balloon 904, the speech balloon 904 may be processed as a non-confirmed message.

If a desired (or alternatively, predetermined) period of time is elapsed after receiving the new message, the information outputter 330 may remove the speech balloon 904 and may process the corresponding message as a non-confirmed message. In this case, referring to FIG. 10, the information outputter 330 may display an identifier 1005 representing presence of the non-confirmed message at a location adjacent to the partner icon 702 having sent the corresponding message, for example, at a right upper end of the partner icon 702.

Referring to FIG. 11, if at least a portion of chat partners included in a chatroom is using a music service, the information outputter 330 may output, on the 3D space 520, a service icon 1106 representing the music service at a location adjacent to the partner icon 702, for example, at a right upper end of the partner icon 702.

Referring to FIG. 12, the information outputter 330 may track a gaze 1200 of the user with respect to the 3D space 520, and may output music being used by a chat partner corresponding to the gaze 1200 of the user through an output device of the electronic device 110. Referring to FIG. 12, when the chat partners A and C are using a music service, the information outputter 330 may output music the chat partner A is listening to if the gaze 1200 of the user stays at the partner icon 702 of the chat partner A. Here, the information outputter 330 may display a mute icon 1207 at a location adjacent to the partner icon 702 of the chat partner C or the service icon 1106. Referring to FIG. 13, the information outputter 330 may track the gaze 1200 of the user. Here, if the gaze 1200 of the user stays at the partner icon 702 of the chat partner A and then moves to the partner icon 702 of the chat partner C, the information outputter 330 may stop outputting music the chat partner A is listening to, and may output music the chat partner C is listening to. Here, the information outputter 330 may apply the effect of gradually decreasing the volume of music the chat partner A is listening to and gradually increasing the volume of music the chat partner B is listening to. If outputting music the chat partner A is listening to is stopped, the information outputter 330 may display the mute icon 1207 at a location adjacent to the partner icon 702 of the chat partner A or the service icon 1106.

In the case of an icon representing another service being used by a chat partner, the information outputter 330 may output the icon on the chatroom represented in a 2D form as well as a 3D space. For example, the information outputter 330 may sort partner icons configured as profile images in order in which messages are received and may display the sorted partner icons on a 2D chatroom. Here, if a chat partner is using the music service, the information outputter 330 may display a service icon at a location adjacent to a corresponding partner icon and may track a gaze of the user and may output music being used by a chat partner corresponding to the gaze of the user through an output device of the electronic device 110.

According to some example embodiments, it is possible to represent a chatroom as a depth-adjustable 3D mode using 3D technology, and to represent a distance from a chat partner as depth information on a 3D space. Also, it is possible to output, as state information associated with a chat partner on the 3D space, a new message, a message non-confirmation state, location information or activity information based on the location information, and/or a use status of another service linked to a messenger account. Also, it is possible to track a gaze of a user with respect to a chatroom and to output state information of a chat partner corresponding to the gaze of the user.

According to some example embodiments, it is possible to reduce usage of memory and at least one processor included in an electronic device of a user because, for example, a distance from a chat partner or a status information associated with the chat partner are intuitively and instantly represented on a 3D space without additional processing or additional communications between users.
